In the last two decades, dozens of spacecraft have explored planets, moons, asteroids, and comets, returning a treasure trove of scientific data. Thanks to generous data release policies and the proliferation of high-speed Internet, the worldwide public has rapid access to huge quantities of spacecraft image data. Skilled amateur image processors produce stunning views of alien places, and represent a valuable and underutilized resource for increasing public support of planetary exploration. I'll present some of the beautiful work being done by these amateurs and discuss ways that they can benefit planetary science.
